[xsl] grouping problem

2010-04-15 17:50:36


I am attempting to group items in a flat file. Here is a sample of the input:

<testbody>
                                <p class="test">A</p>
                                <p class="head-testname">Reading 
Comprehension</p>
<p class="bodytext-directionsrevise">Directions: Read the selection. Then answer the questions that follow.</p>
                                <p class="head-selectiontitle">Jason and the Golden 
Fleece</p>
                                <p class="bodytext-selectionintro">In Greek 
mythology, ....</p>
                                <p class="bodytext-numbered">1 King Pelias of Greece, 
....</p>
                                
<p class="bodytext-question"><span class="x-qnumber-bold">1</ span>The word invincible in paragraph 14 means—</p>
                                <p class="bodytext-choice"> A “full of joy.”</p>
                                <p class="bodytext-choice"> B “not happy.”</p>
                                <p class="bodytext-choice"> C “having good 
judgment.”</p>
                                <p class="bodytext-choice"> D “unable to be 
defeated.”</p>

<p class="bodytext-question"><span class="x-qnumber-bold">2</ span>This story can be described as an epic tale because—</p> <p class="bodytext-choice"> F someone with magical powers helps the main character.</p>
                                <p class="bodytext-choice"> G an ordinary person 
finds courage. </p>
<p class="bodytext-choice"> H a hero travels to perform a difficult task for his country. </p> <p class="bodytext-choice"> J a good character confronts evil forces.</p>

<p class="bodytext- directionsrule1">Directions: Read the selection. Then answer the questions that follow.</p>
                                <p class="head-selectiontitle">Freight</p>
                                <p class="bodytext-selectionintro">This is an excerpt 
....</p>
                                <p class="bodytext-subhead">Cast of 
Characters</p>
                                <p class="oldstyles-normal">ABBY, 13 years 
old</p>
                                <p class="oldstyles-normal">LABAN, a slave 
owner</p>
                                <p class="oldstyles-normal">TUCKER, his 
overseer</p>

<p class="bodytext-question"><span class="x-qnumber-bold">11</ span>Why are some .... parentheses?</p>
                                <p class="bodytext-choice"> A to tell the actors what 
to do</p>
                                <p class="bodytext-choice"> B to tell a narrator what 
to say</p>
                                <p class="bodytext-choice"> C to tell what sound 
effects to use</p>
<p class="bodytext-choice"> D to tell the audience what is going on</p>

</testbody>


Here is the basic grouping 2.0 template (xsl:attribute elements have been removed) in which I am trying to group the @class='bodytext- question and @class=bodytext-choice elements:

 <xsl:template match="testbody">
          <testbody>
<xsl:for-each-group select="*" group-starting-with="p [(_at_)class=('bodytext-question','bodytext-questionfirst')]">
                    <xsl:choose>
<xsl:when test="following-sibling::p [(_at_)class='bodytext-choice'][4]"> <xsl:text>&#10;</ xsl:text><xsl:element name="question">


<xsl:apply-templates select="current-group()"/>

</ xsl:element><xsl:text>&#10;</xsl:text>
                         </xsl:when>
                         <xsl:otherwise>
<xsl:apply-templates select="current- group()"/>
                         </xsl:otherwise>
                    </xsl:choose>
               </xsl:for-each-group>
          </testbody>
     </xsl:template>

This template works for bodytext-questions that are followed by other bodytext-questions. But it also groups everything from the start of <testbody> to the first bodytext-question as well as everything that follows the last of a series of bodytext-questions.

<testbody>
<question>
                                <p class="test">A</p>
                                <p class="head-testname">Reading 
Comprehension</p>
<p class="bodytext-directionsrevise">Directions: Read the selection. Then answer the questions that follow.</p>
                                <p class="head-selectiontitle">Jason and the Golden 
Fleece</p>
                                <p class="bodytext-selectionintro">In Greek 
mythology, ....</p>
                                <p class="bodytext-numbered">1 King Pelias of Greece, 
....</p>
</question>
<question>                                
<p class="bodytext-question"><span class="x-qnumber-bold">1</ span>The word invincible in paragraph 14 means—</p>
                                <p class="bodytext-choice"> A “full of joy.”</p>
                                <p class="bodytext-choice"> B “not happy.”</p>
                                <p class="bodytext-choice"> C “having good 
judgment.”</p>
                                <p class="bodytext-choice"> D “unable to be 
defeated.”</p>
</question>
<question>
<p class="bodytext-question"><span class="x-qnumber-bold">2</ span>This story can be described as an epic tale because—</p> <p class="bodytext-choice"> F someone with magical powers helps the main character.</p>
                                <p class="bodytext-choice"> G an ordinary person 
finds courage. </p>
<p class="bodytext-choice"> H a hero travels to perform a difficult task for his country. </p> <p class="bodytext-choice"> J a good character confronts evil forces.</p>

<p class="bodytext- directionsrule1">Directions: Read the selection. Then answer the questions that follow.</p>
                                <p class="head-selectiontitle">Freight</p>
                                <p class="bodytext-selectionintro">This is an excerpt 
....</p>
                                <p class="bodytext-subhead">Cast of

                                <p class="oldstyles-normal">ABBY, 13 years

                                <p class="oldstyles-normal">LABAN, a slave 
owner</p>
                                <p class="oldstyles-normal">TUCKER, his

</question>
<question>
<p class="bodytext-question"><span class="x-qnumber-bold">11</ span>Why are some .... parentheses?</p>
                                <p class="bodytext-choice"> A to tell the actors what 
to do</p>
                                <p class="bodytext-choice"> B to tell a narrator what 
to say</p>
                                <p class="bodytext-choice"> C to tell what sound 
effects to use</p>
<p class="bodytext-choice"> D to tell the audience what is going on</p>
</question>

</testbody>

I suspect that I should be using group-adjacent but am I unsure how to go ahead with such grouping in this case.
